**YOLOR-comm-mmWave** is a fine-tuned object detection model for BS identification for beam initialization to detect `mmWave radio` in one inference pass. The model is trained on imagery of **[Terragraph Sounders](https://terragraph.com/) from [Meta](https://about.meta.com/)**, deployed in indoor commercial spaces. Part of the YOLOR detector family used for the Look Once, Beam Twice mmWave V2X beam-management pipeline (SECON 2026).

| | |
|---|---|
| **Architecture** | YOLOv11x, 82-class output head (COCO 80 + 2 custom) |
| **Initialization** | stock `yolo11x.pt` |
| **Schedule** | 200 epochs, `cos_lr`, `close_mosaic=20`, `lr0=0.01` |
| **Training data** | IndoorCommercialDataset, perceptual-hash deduped (`cp_dedup.py`, Hamming threshold = 1) — 1,631 train (kept from ~14,386 raw frames) / 1,798 val / 1,799 test |
| **Custom classes** | `radio` (id 80), `mmWave radio` (id 81) |
| **Released checkpoint** | `last.pt` |

## Usage

```python
from huggingface_hub import hf_hub_download
from ultralytics import YOLO

weights = hf_hub_download(repo_id="cpnlab/YOLOR-comm-mmWave", filename="last.pt")
model = YOLO(weights)
results = model.predict("path/to/image.jpg", conf=0.25)
```

Class indices: `0–79` = COCO; `80` = `radio`; `81` = `mmWave radio`.
